'[PIC]: how do I speed up icsp prog. of 12C671 when'
I am working on a project which requires me to program a 12C671 chip through the parallel port. I can write the program to the chip, but do to the 3N additional programming cycles required, the whole process takes about 3 minutes to write the entire memory. Is this normal?
One thing I have noticed is that when I have my clock pulse on for less than 100 uSecs I start getting errors in the data. If I go below 5 uSecs between rise and fall of the clock, it won't program the chip at all.
This my first PIC project, so I don't really know what time frames I should be looking for, or how best to achieve them, so any help would be greatly appreciated.
